About the Lake
Chambers Lake is a water supply reservoir and regional flood control facility of the Chester County Water Resources Authority.
In 1994, the lake was formed by the construction of Hibernia Dam on Birch Run to provide a supplemental source of local drinking water, and needed flood control for the Brandywine Creek watershed. The lake also offers excellent recreational opportunities such as fishing, boating, hiking and bird watching.
In September 1996, the lake was officially dedicated as Chambers Lake, in memory of J. Franklin Chambers, the first superintendent of Hibernia Park.

Hibernia Dam Rehabilitation Project 2020
Chester County Water Resources Authority and USDA Natural Resources Conservation Service are undertaking improvements to the Hibernia Regional Flood Control Dam located at Hibernia County Park. The work will involve construction activities beginning June 8 and anticipated to be completed by October 31. The improvements will enhance the structural capability of the dam to meet updated design standards and to extend the life of the Hibernia Dam and Chambers Lake for an additional 50 years.
To protect the safety of Park visitors during the construction activity, public access will be prohibited to the areas in the immediate vicinity of the dam. The work being performed will not affect Chambers Lake or its use.
For more information, please contact Chester County Water Resources Authority (dam owner) at 610-344-5400 or [email protected], or visit our website at chesco.org/water
Fishing + Boating
Fishing is permitted 24 hours a day. The lake is stocked with warm water species, including Panfish, Channel Catfish, Chain Pickerel, and Smallmouth and Largemouth Bass. Chambers is one of only a few Pennsylvania lakes that is a Panfish Enhancement Area, which regulates the number, quality and size of panfish through minimum length limits. It is also one of a select few in the Big Bass Program.
A public fishing pier is open on the lake’s north side and can be accessed from the Lake Trail. Other shoreline fishing is permitted, but is prohibited from the dam breast itself. There is a public parking lot and boat ramp located off Wagontown Road. After park hours, parking is permitted for fishing only.
The northern end of the lake is designated as a wildlife sanctuary and is closed from April 1st through June 15th to all lake and shore activities in this area.
